Last year, Ushahidi won the Netsquared Mashup challenge, which propelled the project from just a collaborative initiative, to an actual open source project. We’d like to encourage organizations testing the Ushahidi engine or other organizations using mobiles for social change to apply for the N2Y4 Mobile Challenge.
More information, including guidelines, key dates and the challenge process can be found on the N2Y4 site, do check it out.
